LUBRICATOR.

SPECIFICATION forming part of Letters Patent NO. 586,714, dated July 20,1897. Application filed April 16, 1897. Serial N- 632,393. (No model.)

To CbZZ whom it may concern:

Be it known that I, JOSEPH K. REESE, a citizen of the United States,residin at Roanoke, in the county of Roanoke and State of Virginia, haveinvented certain new and useful Improvements in Triple-Feed Lubricatorsfor Steam-Engines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to lubricators of that type wherein the oilcontained within the oilreservoir is displaced by the water of condensation of steam entering therein and caused to flow through theoil-supply passage leading to the parts to be lubricated.

The object of my invention is to provide a triple-feed lubricator forsteam-engines having connection with and adapted to lubricate the twocylinders on opposite sides of the engine and the movable parts inclosedwithin the p Limp-cylinder of the air-brake mechanism.

In carrying out these objects my invention consists in certain noveldetails of construction, combinations, and arrangements of partshereinafter more fully described, and specifically set forth in theappended claims.

In the accompanying drawings, Figure 1 is a side elevation view of anoilcr constructed in accordance with my invention. Fig. 2 is a top orplan view of the same. Fig. 3 is a longitudinal section taken throughthe center of the valve-casing and oil-reservoir,showing theconstruction of the parts thereof. Fig. l is a central verticalsectional view of the oil-reservoir, taken on a line at right angles tothe section shown in Fig. 3.

Referring to the drawings, the numeral 1 designates the valve-case of alubricator which is adapted to be secured within the cab or adjacent thecab of a locomotive. This case is constructed of two sections 2 3,fitted together and connected by bolts 4:. Said sections are provided atthe center with a longitudinal opening 5, which constitutes aninspection or peep-sight opening, whereby the feed of the oil throughthe sight-glasses may be readily inspected, as will be hereinafterdescribed.

The numeral 6 designates the oil-reservoir, to which a steamdome-7 isconnected, said dome being provided with a threaded nipple 8, havingconnection with the steam-supply pipe. The oil-reservoir is provided atthe top with a division-wall 9, extending horizontally below the openingat the top thereof and nearly closing the said opening and provided withan extension 10, projecting parallel with one side wall of the reservoirand forming a port or passage 11 for access of condensed steam into thebody of the reservoir. The reservoir is also provided with a seconddivision-wall 12, extending from the bottom of the said firstdivision-wall immediately below the top opening of the reservoir andthence extending parallel with the side wall of the case opposite thedivision and forming a port or passage 13 for the passage of live steam.A short tube 11- screws into the horizontal part of the division-wall 9and is in line with the opening into the port or passage 13, while theupper end of said tube terminates a little above the center of thesteamdome.

An oil-eduction tube 15 extends up from the bottom of the oil-reservoirto near the top thereof and is adapted to carry off the oil displaced bythe water of condensation, which flows out into the oil-supply pipe 16,leading to the valve-casing 1, a controlling-cock case 17 and cock 18being connected with and interposed between the said oil-tube andoilsupply pipe to control the passage of oil therethrough. The steamport or passage 13 is in communication with the stcam-supply pipe 19,leading to the valve-ease, the passage of steam therethrough beingregulated by a case 20, having a cook 21 connecting the reservoir andsaid steam-supply pipe.

It will be understood that in operation when the steam-dome is full ofsteam a portion of the steam will pass through the short tube 1% and thesteam port or passage 13 and steam-supply pipe, and the condensed steamwill also pass through the port or passage 11, formed by thedivision-walls 9 10, into the oil-reservoir, the water of condensationserving to displace the oil, which will overflow into the oil-eductiontube and out from the same into the oil-supply pipe.

The oil-reservoir is provided with an opening 22 therein for filling thesame with oil and is also provided with a gage-glass 23, whereby theamount of oil remaining in the reservoir may be readily ascertainedwhenever desired.

The valve-case 1 is provided with a steam port or passage and anoil-supply passage 25, the steam-passage extending vertically throughone end of thevalve-case and thence horizontally across the top of thecase, while the oil-passage extends horizontally along the bottom of thecase and at its terminus communicates with a waste outlet or passage 26,controlled by a plug-valve 27. The end of the steam-supply pipe 19 isconnected with a screw-plug 28 by a union or screw collar 29, said plughaving an opening therethrough in communication with the said steam portor passage in the valve-case, while the oilsupply pipe 16 is similarlyconnected with a screw-plug 30 by a screw collar or union 31, said plughaving a passage oropening in communication with the oil-supply passage.

The sight-glasses or feed-tubes 32 34 are contained within theValve-case and exposed at the longitudinal opening 5 therein. The lowerends of these feed-tubes are seated in sockets in screw-plugs 35 andconfined within the case at the top and bottom of the said opening byscrew collars 36. The screwplugs are connected with the valve-case atthe bottom thereof and project through the oil port or passage therein,being provided with circumferential grooves 37 to permit the oil to passfreely around them and feed-openin gs 38, leading to oil-passages 39 insaid plugs, the said passages being controlled by valves 40. Nipples 41are screwed into the said plugs at the upper end of the oil-passagetherein and project into the feed-tube and are adapted to permit a smallquantity only of the oil to pass into the tube. The steam port orpassage in the valve-casing is also in communication with the feed-tubesat the upper end thereof by means of passages 4-2, said passages beingcontrolled by valves 43. In operation the steam passing through saidport or passage enters into the feed tubes and condenses therein untilthe water of condensation completely fills the said tubes, whencondensation ceases. The oil passing through the oil-supply passage inthe base of the valve-chamber enters into the passage 38 of thescrew-plugs 35 and passes out through the nipples 4:1 and is fed up dropby drop through the sightglasses and out into the steam-supply pas sage24. In the present instance the valvecase has pipe connections L4 454:6, adapted to extend to and be respectively connected with the twosteam-cylinders of the engine and the air-brake cylinder forsupplyinglnbricant thereto to lubricate the movable parts thereof.

My invention provides a simple and effective construction of triple-feedlubricators, by means of which the two steam-cylinders and the air-brakecylinders of an engine may be quickly and efficiently lubricated.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In triple-feed lubricators for steam'engines, the combination of anoil-reservoir having a steam-dome, an oil-eduction tube and twoindependent ports or passages for steam, one leading to the interior ofthe reservoir and the other to the exterior thereof, a valve-caseprovided with a longitudinal opening and steam and oil ports or passagesleading to pipes having connection with the two steam-cylinders and theair-brake cylinder of a locomotive, three feed-tubes within thevalve-case and exposed at the said opening, and steam and oil supplypipes connecting between the oil-reservoir and valve-ease, substantiallyas'described.

2. In triple lubricators for steam-engines, the combination of anoil-reservoir having a steam-dome, and two independent ports or passagesfor steam, one leading to the interior of the reservoir and the other tothe exterior thereof, a tube lat in communication with the latter portor passage and extending up into the steam-dome, a valve-case consistingof two separable sections provided with a longitudinal opening, asteam-passage extending from the bot tom to the top thereof and thencelongitudinally above said opening, an oilpassage in the bottom of thecase below said opening, three sight-feed tubes within the valve-caseand exposed at the said opening, said tubes connecting the oil and steampassages and provided at the lower ends thereof with feed-nipples,valves controlling the supply of oil thereto, and supply-pipes connect-7 7 ing between the oil-reservoir and the steam and oil supply passagesof the valve-case, substantially as described. 1

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
